4,4-Dimethyl-2,6-piperidinedione Use and Manufacturing

A suspension of LiAlH4 (5.5 g, 145 mmol) in diethyl ether (300 ML) was treated in portions with PREPARATION F F. 4. 4-Dimethyl-rhoiperidineLithium aluminium hydride (3.36g, 88.55 mmol) was suspended in anhydrous THF (89 ml) and the suspension was cooled to 0 0C. 4, 4-dimethylglutarimide (5g, 35.42 mmol) was partially dissolved in anhydrous THF (89 ml) and this was added dropwise to the suspension of lithium aluminium hydride, maintaining the temperature of the reaction mixture between 0 and 3 0C. The reaction mixture was then heated at 55 0C for 30 minutes. The reaction mixture was then cooled to 0 0C and an aqueous IN sodium hydroxide solution (50 ml) was added dropwise. The reaction mixture was filtered through Celite, washing through with THF and water. The filtrate was evaporated in vacuo to remove most of the THF. The aqueous phase was extracted with diethyl ether. The organic phases were separated off, dried (MgSO^ and evaporated in vacuo to afford the title compound as a yellow oil (2.4 Ig, 60%).
